I’ve been chasing up some Neolithic rope. From what I’ve found, most opinion is that in England at the time of the Stonehengineers they would have used rope made from the “bast” fibre under the bark of Lime (Linden) trees. (Perhaps someone could check that I’m right about that).
I had in mind several ideas:
To get just a bit to have on display, or use in a non-crucial bit of the exercise, OR if it was good enough and we could afford it, to get it tested and certified and then try to persuade the authorities to let us use it.
Anyway, I’ve finally found someone who is willing to help us. She is Norway’s only professional ropemaker and she is with a museum that supplies traditional and archaic ropes, mainly for historic sailing ships. http://www.museumsnett.no/hfs/eng/verft/reipslaging.html

I’ll send her long and interesting reply through on the stonehengineers email system.

Perhaps we could decide if we want to take this further, and if so how far. She seems like she’d be very pleased to be involved.
